Car bumpers are used for safety protection, decorating vehicles and improving the aerodynamic characteristics of vehicles. From a safety point of view, the car can play a buffering role in a low-speed collision accident, protect the front and rear car bodies, and can be used in the event of an accident with pedestrians. play a certain role in the protection of pedestrians.

effect.
The front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but are more importantly a safety device that absorbs and mitigates external impact forces, protects the body and protects the body and occupants. From the appearance, the bumper is decorative and becomes an important part to decorate the appearance of the car; at the same time, the car bumper also has a certain aerodynamic effect.
At the same time, in order to reduce the injury to the occupants of the car in the event of a side collision accident, a door bumper is usually installed on the car to enhance the anti-collision impact force of the car door. This method is practical, simple, and has little change to the body structure, and has been widely used. What are the uses of bumpers?
1. Disperse the impact force: When the vehicle collides, it first touches the bumper, and then the bumper transmits the force to the energy-absorbing boxes on both sides to the left and right front longitudinal beams, and then to other structures of the body.
2. Pedestrian protection: I saw on the Internet that the bumpers of some vehicles are made of foam, and I thought it was cutting corners. It’s true, it was actually made of steel before, but considering how scary the people who were involved in the accident were. The bumper replaced with plastic and foam can relieve the impact force on the pedestrian’s legs, especially the calf, and cooperate with the reasonable design of the front bumper to reduce the degree of injury to pedestrians when they are hit. If a really bad bumper can cause a lot of damage to the parts of the car
